OIL-BURNER.

Specification of Letters Patent;

Patented Jan. 5, 1915.

To all whom it may concern uBe it known that I, VVALLACE VVrLson,residing at Seattle, in the county of King and State of Washington, haveinvented a certain new and useful Improvement in Oil-Burners, of

Wh'ich-the'followin'g 1s a specification.

-My invention relates. to improvements in oiL-burners that are adaptedto be placed Within the fire box of an ordinary cooking or-heating stoveand that are further adaptedito burn liquid fuel, as crude oil,kerosene,

E gasolene, and the like, and the object of my improvement is to:provide a simple and efficient burner that may be connected W1th apressure tank that may contain certain liquid-fueland water which may beconducted: to such'burner to be burned in the formiof -gases. Iaccomplish this Ob]6Cl3 by devices .illustrated in the accompanymgdrawings in which- Figure 1 is a view in frontelevatlon of a r:burnerembodying my inventibn as it appears when disposed within the firebox of a stove and associated with a fuel tank ready for use, Fig. 2 isan enlarged view partly in vertical section and partlyifnside elevationof a burner body embodied in my invention, Fig. 3 is a view in verticalsection of a fuel tank that is embodied in my invention, and Fig. tie aview in vertical section of a detail of my invention; f

Like reference numerals indicate like parts throughout the drawingsReferring to the drawings, 6 is an ordinary kitchen stove, 7 is an oilburner d1sposed upon the grate withinthe fire box of said stove 6. Afuel supply tank 8 is disposed near said stove 6 and divided into twoseparate compartments. A fuel supply pipe 9 leads from the tank 8 to theburner 7 for conducting fluid fuel to the point of combustion and awater supply pipe 10 forms a connection between the tank 8 and theburner '7 through Which water may be conducted to the burner 7 there tobe converted into steam to aid combustion.

Referring to Fig; 2 of the drawing, 11 is a concavo-convex saucer shapedmember that forms the base of an oil burner, 12, 12 are legs upon whichthe base 11 is, suported, 13 is a boss disposed concentrically on thelower convex'surface of the base 11, such boss beposed approximately inthe center of the base 11,

legs 1? face of the base 11 within the space inclosed by the ridge 15which ridge 15 serves to keep the deflector 16 always in the centerof-the base 11 and to form a receptacle for Water that may flow out ofthe pipe 10. A perforated flange 18 is provided on the edge of the base11 and a pipe 19 that is connected with the fuel supply pipe 9leadsupwardly through the perforation in such flange 18 and is formed into ahelical coil 20 that is disposed concentrically with the base 11, ashort distance above such base, such coil terminating in a U shaped loop21. which presents a downwardly projecting end 22 above the center ofthe helical coil 20, said end 22 being adapted to be closed by a cap 23which is formed like a butterfly nut that it may be more easily removed,which cap 23 is provided with perforations 24c, 24 where by fuelmay beemitted downwardly therefrom through the helical coil 20. The top andbottom end portion of the helix 20 comprising the loop 21 and the lowerend of the pipe 19 are each filled with wire gauze 25- with its convexside uppermost, the belng adapted to rest upon the sur- The fuel tank 8is formed with an upper i water compartment 26 and a lower oilcompartment 27. An inlet pipe 28 is provided in the water compartment 26and a similar inlet pipe 29 is provided in the fuel compartment 27whereby Water and fuel may be introduced into these respectivecompartnlentsg such inlet pipes 28 and 29 each being provided withsuitable caps 30 and 31 by means or which their top ends may be tightlyclosed.

32 is an outlet pipe connecting the water supply pipe 10 with the watercompartment 26, such pipe '32 being provided with a valve I outlet pipethat connects the fuel supply pipe 9 with the fuel compartment 27, suchfuel outlet pipe 34 being provided with a valve 35 by means of which thesupply of fuel delivered through such pipe may be regulated or may beentirely shut ofl.

An air pump 36 of any suitable form is provided in the top of the fueltank 8, and

is adapted to extend downwardly into the water compartment 26, said pump36 being provided on its lower end with a valve that acts to permit airto be expelled from the lower end of the pump but acts to prevent air orwater from being drawn in at the bottom end of such pump, said valveconsisting in a reducing member 37 that is provided inthe lower end ofthe pump cylinder which reducing member 37 is adapted to be closed by avalve disk 38 having a plate 39 of rubber or like material on its topside that is held in contact with the lower end of the reducing member37 by a helical tension spring 40 as illustrated in Fig. 4. 1

A pressure gage 41 is provided on the top end of a pipe 42 which extendsdownwardly through the top ,of the fuel tank 8 and through the watercompartment 26 and communicates with the oil compartment 27, a smallhole 43 beingprovided in the pipe 42 at a point near the top of thewater chamber 26 whereby pressure within the two chambers 26 and 27 maybe equalized.

In the operation of a burner containing my invention as shown anddescribed the device is set up, as illustrated in Fig. 1, with the bodyof the burner disposed within the fire box of an ordinary stove and thefuel tank Slocated at any convenient point adjacent thereto. The fuelsupply 'pipe 9 is provided-to communicate between the fuel compartment27 of the tank Sand the burner coil 20 and the water supply pipe 10 isprovided to communicate between the water compartment 26'of the tank 8and the base portion 11 of the burner. 'W'hen the burner is to belighted the pressure within the tank is raised to any desired amount byoperating the pump 36. The valve 35 is then opened slightly to admitfuel to flow through the pipe 9 into the coil 20 through which coil itrises into the loop 21 and is emitted downwardly through theperforations 24 on to the convex top surface of the deflector 1(3, andthence it flows oil of such deflector 16, into the bottom of the saucershaped base 11. When enough fuel has collected within the base 11 toheat the coil 20 sufliciently to vaporize the fuel contained thereinthe'valve may be closed and the fuel within the base 11 is ignited toburn to vaporize the fuel within the coil 20 and to heat the base 11 andthe deflector plate l6-to a high temperature, thus causing vapor insteadof liquid fuel to be emitted from the perforations 24 to burn within thecoil .20 and to be deflected outwardly by the deflector 16 to burn abovethe base 11.

As soon as the burner is sufiiciently heated the valve 35 may be openedagain to a desired degree to regulate the flow of fuel at a rateproperly to feed combustion andthe valve 33 may be opened slightly topermit a small amount of water to flow through the pipe 10 and upwardlythrough the perforation 14 to spread out over the bottom of that portionof the heated base llthat much hotter flame than could'be obtained Iwith the vaporized fuel only.

Obviously changes in the details of construction and form of variousparts of my device may be resorted to without departing from the spiritof my invention or sacrificing any of its advantages.

What I claim. is:

1. In a burner of the class described, the combination with a saucershaped base portion, of a c irved deflector disposed above the centralpart of said base portion, a helix of pipedisposed above said baseportion, said helix of pipe being connected with a. suitable source offuel supply and adapted 1 to emit fuel downwardly on to said curved 2.In a burner of the class described, the

combination with a saucer shaped base portion, of an annular ridgeconcentrically dis posed on the upper surface of said base portion, acurved deflector disposed above thevcentral' part of said base portion,a. water supply pipe communicating with'said base portion to deliverwater within the space inclosedibygsaid annular ridge, a helix of ipedisposed above said base portion the lower end of said pipe beingconnected with a source of fuel supply and its upper end portion dieingformed to project downwardly above said helix and provided with aperforated cap through which fuel may be emitted downwardly, and apressure. tank for fuel and water.

3.,In a burner of the class described, the combination with a baseportion that may form a receptacle for liquid, of a'helix of pipedisposed above said base portion and connected with a source of fuelsupply, aw-
